摘要
对不同强度等级的砼、不同直径的圆钢和变形钢筋制成的18根煤矸石砼轴心受拉构件裂缝的开展，以及其变形规律进行分析讨论，并提出裂缝宽度和刚度的计算公式．
Eighteen stretched members with coal gangue-concrete shafts are made of concrete of differentstrength grade and round steel and deforming iron reinforcement of different diameter. The authors analyseand discuss the development of their breaks and regular pattern of their deformation:and prosent a formulafor computing the breadth of the break.
